Executive summary

This paper provides guideline about how to set up the Dell DR Series System as a backup to disk target for

RMAN® over CIFS/Rapid CIFS and NFS/Rapid NFS.

For additional information, see the DR Series system documentation and other data management

application best practices whitepapers for your specific DR Series system at:

http://www.dell.com/powervaultmanuals

Note: The DR Series System/RMAN build version and screenshots used for this paper may vary slightly, depending on

the version of the DR Series System/ RMAN software version used.

About RMAN

RMAN (Recovery Manager) is a backup and recovery manager supplied for Oracle databases by the Oracle

Corporation. Oracle Corporation recommends RMAN as its preferred method for backup and recovery

and has written command-line and graphical (via Oracle Enterprise Manager) interfaces for the product.

The following illustration shows a typical implementation of the backup infrastructure with the Dell DR

Series system. The DR Seriees system offers optimized replication of data from one system to another over

the WAN for disaster recovery.

1 Installing and configuring the DR Series system

1. Rack and cable the DR Series system, and power it on. Initialize the DR Series system.

In the

Dell DR Series System Administrator Guide

, refer to the following topics: “iDRAC

Connection”, “Logging in and Initializing the DR Series System and “Accessing IDRAC6/Idrac7

Using RACADM” for more information.

2. Log on to iDRAC using the default address 192.168.0.120, or the IP address that is assigned to the

iDRAC interface, with the user name and password: “root/calvin”.

3. Launch the virtual console.

6 Setting Up the Dell™ DR Series System as an NFS or CIFS Backup Target on Oracle Recovery Manager® |

4. After the virtual console is open, log on to the system as user administrator with the password

St0r@ge! (The “0” in the password is the numeral zero).

5. Set the user-defined networking preferences.

6. View the summary of preferences and confirm that it is correct.

7 Setting Up the Dell™ DR Series System as an NFS or CIFS Backup Target on Oracle Recovery Manager® |

7. Log on to DR Series system administrator console using the IP address you just provided for the

DR Series system with the username administrator and password St0r@ge! (The “0” in the

password is the numeral zero.).

8. Join the DR Series system to Active Directory.

Note: If you do not want to add the DR Series system to Active Directory, please see the

DR Series

System

Owner’s Manual

for guest logon instructions.

a. Under System Configuration in the left navigation area, click Active Directory.

b. Enter your Active Directory credentials.

9. Create and mount the container by selecting Storage > Containers in the left navigation area, and

then clicking Create at the top of the page.

Note: For improved security, Dell recommends adding IP addresses for the Backup console (RMAN). Not all

environments will have all components.

15. Click Create a New Container, and then confirm that the container is added.

16. Select the Container that was just created and click Edit. Note the container share/export path,

which you will use later to target the DR Series system.

2 Configuring a backup job on RMAN over a CIFS target

2.1 Oracle settings for Windows RMAN Online Backup

There are two options for RMAN to authenticate to the DR Series system through CIFS.

 DR is joined into an Active Directory Domain: Integrate RMAN Node and DR Series System with Active

Directory

 Ensure the AD user has appropriate ACLs to the DR Series System Container share

 DR is standalone CIFS server: Make sure this CIFS user has appropriate access permission to the DR

Series system container share. Oracle RMAN Backup Node will use this user to authenticate to DR

Series system share in Workgroup mode.

 To set the password for local CIFS administrator on the DR Series system, log on to the DR

using SSH.

i. Log on with the username Administrator, and password St0r@ge!

ii. Run the following command:

authenticate --set --user administrator

Note: The CIFS administrator account is a separate account from the administrator account used to

administer the appliance. After an authentication method is chosen, set the RMAN Oracle service

account to use the CIFS administrator account.

2.2 Default RMAN backup configuration

The Default settings for RMAN are listed below with command show all.

2.3 RMAN backup settings to DR Series system backup

The RMAN backup settings changed for taking backup to Dell DR Server systems over CIFS.

1. Configure channel to use UNC path of the DR Series system container.

13 Setting Up the Dell™ DR Series System as an NFS or CIFS Backup Target on Oracle Recovery Manager® |

CONFIGURE CHANNEL DEVICE TYPE DISK MAXOPENFILES 1 FORMAT ‘\\<UNCPath to

the container noted above >/ora_df%t_s%s_s%p’;

2. Configure RMAN to back up the control file after each backup.

2.4 RMAN backup of full database

3 Replicating Oracle RMAN database images

First, you need to create containers on the source and target DR Series systems and then configure

replication between those source and target DR containers. Both of the DR Series systems should be on

the same version. Refer to the

Dell DR Series System Administrator’s Guide

for information about

configuring cascaded replication.

Replication of Oracle Database to target DR Series system

3.1 RMAN restore from replication DR Series system container

To restore the Oracle Database from replication container, first detach the replication on the target

container, and run the following commands to import the backup images into the RMAN Catalog.

RMAN> catalog start with '<UNC Path of the DR replication container>';

Searching for all files that match the pattern <UNC Path of the DR replication

container>

4 Configuring a backup job on RMAN over an NFS target

4.1 Create a storage device for NFS

For NFS backup using RMAN, a target folder needs to be created as an NFS share directory. This is the

location to which backup objects will be written. (This is not required while adding CIFS share.)

1. Mount the DR Series System NFS share onto the NFS share directory which backup objects will be

written in the RMAN environment.

2. For example:

mount –t nfs <ip address of DRXXXX>:/containers/sample

/mnt/RMANtargetContainer

3. Verify the NFS share. One way is to try using the Linux command “cat /proc/mounts”. The rsize

and wsize of the connects in the command output should be 512K.

In the RMAN settings use the below command to add the NFS mount path as device.

CONFIGURE CHANNEL DEVICE TYPE DISK MAXOPENFILES 1 FORMAT '/<Mount point path

on RMAN server>/ora_df%t_s%s_s%p';

Note: Please follow the instructions in Section 3 as the backup and other settings are the same as that of

CIFS.

5 Creating a storage device for Rapid CIFS

5.1 About the Rapid CIFS plugin

Rapid CIFS enables write operation acceleration on clients that use CIFS file system protocols. These

accelerators allow for better coordination and integration between DR Series systems backup, restore, and

optimized duplication operations with Data Management Applications (DMAs) such as CommVault, EMC

Networker, and Tivoli Storage Manager. For a current list of supported DMAs, see the

Dell DR Series

System Interoperability Guide.

Rapid CIFS is a Windows-certified filter driver that ensures that only unique

data is written to the DR Series system. All chunking and hash computations are done at the client level.

5.2 Configure Rapid CIFS

To configure Rapid CIFS on windows operating systems download and install the plugin

DellRapidCIFS-xxxxx.msi on the Oracle server.

Refer to the

Dell DR Series System Administrator’s Guide

for the download location and for more

information.

Below is the output for Rapid CIFS configured backup.
